‘R’ will be the first part of the given sequence as ‘this fallacy’ is used in relation of the sentence mentioned in S1, hence making a pair with it. ‘Q’ will follow next as it is talking about the glance at the scores to determine the difference between the understanding between fast and slow readers in terms of comprehension, hence making a pair with the previous part. ‘P’ will follow next as it furthers the talk about the aspect of comprehension of slow readers. ‘S’ will make a pair with S6 as ‘This statement’ in S6 refers to the statement made in ‘S’. Hence, RQPS is the correct sequence. Thus, option (a) is correct.
